1 Optimizing Monitor Performance
Use Caution When Setting Up the Monitor
To prevent damage to the monitor, do not touch the surface of the LCD panel. Pressure on the panel
may cause non-uniformity of color or disorientation of the liquid crystals. If this occurs the screen will
not recover to its normal condition.
If installing a base, lay the monitor face down on a flat surface covered with a protective sheet foam
or non-abrasive cloth. This prevents the screen from getting scratched, defaced or broken as well as
damage to the front panel buttons.
